Good question. Because now, there's a religion just for atheists, based on two simple principles, the second an application of the first, and the first derived straight from evolution itself. This religion corresponds exactly to the core of the existing religions.

It's not so much imposing them on myself as being guided by these principles, and I find that they serve me brilliantly. It's not like a magic wand though, sometimes I need to get guidance off other people who also follow the same principles.
